Solar Panel Connection Guidance
The inverter operates within a voltage range of 55-450Vdc. If a voltage lower than 55Vdc is connected, the inverter may not detect the installation.
To calculate the number of panels needed, consider the maximum supply voltage (Vmp). For example, if a panel has a Vmp of 34.89V, two panels in series would provide 69.78Vdc (34.89Vmp * 2). It is recommended to add one more solar panel to compensate for voltage loss between the panels and the inverter.
Important Installation Note
All inverters are delivered in the OFF mode. Ensure the inverter is turned ON after completing the installation. The LCD display will illuminate when PV load is detected, regardless of the ON/OFF button's state, which might cause confusion.
